Centralized
Centralized
The centralized photovoltaic storage system achieves the three in one function of “power generation+peak shaving+backup” by combining large-scale photovoltaic arrays (starting from 50MW) with energy storage stations (usually configured at 15% -30% of the installed photovoltaic capacity). The system consists of photovoltaic modules, PCS converters, energy storage batteries (mainly lithium iron phosphate), energy management systems (EMS), and boosting stations, supporting grid connected/off grid dual-mode operation.
Target Customers
grid operators, cross regional transmission nodes, large-scale wind and solar bases, high energy consuming industrial parks, mining/port clusters;
Project Planning and Design
– Scope: Site assessment, system design, and project configuration.
– Goal: To ensure a well-structured and efficient design for optimal performance.
Engineering Services
– Scope: Commissioning guidance, on-site services, and grid-related modifications.
– Goal: To deliver the project with high quality and efficiency.
Maintenance Services
– Scope: 24/7 online support, technical assistance, and spare parts service.
– Goal: To ensure prompt responses and long-term operational reliability.
Training Services
– Scope: Technical training, emergency drills, and systematic assessment and certification.
– Goal: To standardize safe production and operations, and support talent development.
Economy
If the LCOE is less than 0.25 yuan/kWh, the energy storage system can increase the IRR to 8% -12% through peak valley arbitrage.
Grid friendly
Provides ± 10% power rapid adjustment capability to alleviate the pressure of new energy consumption.
Land intensification
By using high-density supports and tracking systems, the unit MW of land is reduced by 20%.
Policy dividend
Enjoy dual benefits of renewable energy subsidies and energy storage capacity leasing.
Collaboration mode
EPC general contracting mode: providing integrated services of “design procurement construction”, covering power station site selection evaluation, system capacity configuration optimization, power grid access scheme design, etc. Advantages: Zero technical barriers for homeowners, risk transfer throughout the entire process.
Energy management cooperation: Adopting a “construction+operation” sharing model, we bear the initial investment and recover costs through the sharing of power generation revenue (such as an 80:20 sharing ratio). Applicable scenarios: Industrial and commercial parks, large-scale infrastructure projects.
Financial leasing model: Joint financial institutions provide equipment financing services, and owners repay equipment payments in installments based on power generation, with property rights transferred upon expiration.
Pre sales, implementation, and after-sales full cycle service
Pre sales: Requirement diagnosis: Conduct site selection evaluation through drone mapping and shadow analysis software. Scheme design: Provide 3 sets of differentiated configuration schemes (such as 1C/0.5C battery system selection). Economic verification: Use PVsyst simulation to produce a 20-year attenuation prediction report.
Implementation: Construction management: adopting modular construction (photovoltaic array → PCS cabin → energy storage container), grid connection service: including power quality inspection, protection value calculation, dispatch agreement signing, system debugging: completing 72 hours of continuous charging and discharging test+grid related characteristic test.
After sales: intelligent operation and maintenance: deployment of AI warning platform (component PID repair reminder, battery SOH monitoring, performance guarantee: providing 98% availability commitment for the first year+0.8% annual attenuation compensation clause, value-added service: electricity market trading agent (participating in peak shaving auxiliary service quotation).
